Yeah I was off it four or five days a couple weeks ago because I left it at my friend's house two hours away and instead of going up there, he offered to send it down to me. It definitely too a lot longer than I expected....
I had similar PMS-like symptoms to Melody. Hot Flashes, crying spells, restlessness. Probably would've gotten angry if there was someone for me to get angry at (my one roommate was out of town and during the summer there's not many people still in the college town where my apartment is). Most of all, there was the severe discomfort of having "it" attempt to be active again. Fortunately, by breasts seemed to still be growing, so I don't think that being off it for a short period of time will do much harm, if any. My friend said she was off for two weeks once and it was fine. According to her, the estrogen stays in there for about two weeks.
